Throughput Maximization by Time Switching in Multipoint WBAN With Fairness Consideration

Abstract

In this paper, the average throughput maximization challenge with resources fairness consideration is proposed. In a multipoint wireless body area network (MP-WBAN), the time switching (TS) strategy and fairness algorithm are studied to improve system resources allocation performance. Under extreme circumstances, the sensors transfer command signals to the access point (AP) requesting the radio frequency (RF) energy from the source node. On the other hand, the sensors attached to the body surface transmit the perceived physiological information to the AP node. Owing to distance-dependent signal attenuation, the sensors near the AP node harvest more RF energy and time slots to achieve higher throughput. On the contrary, the sensors farther from the source node receive fewer RF energy and time slots to obtain lower throughput. Therefore, we design the common throughput maximization algorithm to allocate more time to farther sensors. At last, the effectiveness and accuracy of the studied fairness scheme are verified by simulation experimental data.

Enhancing Throughput Cluster-Based WBAN Using TDMA and CCA Scheme

“…In the work of [8], they proposed an enhanced throughput by varying multipoint in a wireless body area network with an even distribution. In their work, the nodes send an authorized signal to the gateway by requesting the radio frequency power from the source.…”

Practical pairing-Free sensor cooperation scheme for cloud-Assisted wireless body area networks

“…Sensitive biomedical data is then transmitted to the remote server via PC. WBAN sensors (includes wearable and implantable sensors) are the low-power wireless medical devices subject to computing, communication, power supply, and storage (Liu et al 2020;Anjum et al 2020). On the other hand, increasing the calculation and transmission load on the sensor side will release more energy into heat and eventually damage the human organs.…”

“…The effective authentication mechanism between wireless entities is mandatory, providing preliminary protection for WBAN interactions (Shen et al 2016;He et al 2017). Therefore, various charts and unknown security threats such as eavesdropping, impersonation, message replaying can be prevented (Liu et al 2020). After mutual authentication, efficient group key distribution and management of all verified wearable sensors is of great significance (Anjum et al 2020).…”
